Maintenance

All moving parts are long-termlubricated for a normal operationalenvironment. We recommend a checkand lubrication of the linear actuator,and if necessary a change of wornparts, after every 12th month or3000 km travel of distance, depen-ding on the type of application.Please see separate instructions.

Commissioning

The products in this datasheet shouldnot be operated until the machine/application in which they are used haspassed necessary inspection.

Installation Instructions

Use the threaded holes in the free endcap and a mid-section support close tothe motor end for mounting the linearactuator.The linear actuator can be fitted in anyposition. To prevent contamination suchas fluid ingress, the actuator should befitted with its sealing band facingdownwards.

SizingPerformanceOverviewMaximum Loadings

Sizing of Linear Actuator

The following steps are recommendedfor selection :

1. Check that the maximum values inthe adjacent chart and transverseforce/stroke graph below are notexceeded.

2. Check the lifetime/travel distance ingraph below.

3. When sizing and specifying themotor, the RMS-average torquemust be calculated using the cycletime in application

TransverseForce/strokeThe permissible transverse force isreduced with increasing stroke length.
